To provide a latch lock that can be easily dug into a door and that can change the right and left-handedness of a latch without using a front plate, and an operation member suitable for the same.SOLUTION: A lock case is formed by two cylinders partially overlapping each other in the vertical direction to form an almost figure-eight column shape, and in the resulting inner space a latch, a hub with a square hole, a latch spring, a swinging member, a slide member, a rotating pipe member, and a stopper member are placed. A latch lock is inserted from the front face of a door into a dug-in part which is formed such that two processes are carried out by staggering the seating by a circular cutting tool from the front face of the door by a certain distance in the vertical direction, an operating member made up of a handle with a square shaft and a pedestal is provided, and after fixing the latch lock and the pedestal, the handle is mounted with the square shaft inserted into the square hole of the hub. The right and left-handedness of the latch lock can be changed by operating the stopper member located on the lock case in the upward direction, rotating the rotating pipe member 180 degrees together with the latch, and then pushing down the stopper member again.SELECTED DRAWING: Figure 1
【課題】 扉への掘り込みが容易であり、かつフロント板を用いることなくラッチの左右勝手が変更可能なラッチ錠と、それに適した操作部材を提供する。【解決手段】 錠ケースを２個の円筒を上下方向に一部重ね合わせた略８の字柱状にて形成し、その内部にラッチと角孔を有したハブとラッチばねと揺動部材とスライド部材と回転パイプ部材とストッパー部材を配置する。扉の戸先面から円形の切削工具による座繰りを上下方向に一定距離ずらせて２工程実施した掘り込み部分に、ラッチ錠を戸先面から差し込み、角軸を有するハンドルと台座からなる操作部材を設け、ラッチ錠と台座を固定した後に角軸をハブの角孔に挿入した状態でハンドルを装着する。錠ケースに配置されたストッパー部材を上方向に操作し、ラッチと共に回転パイプ部材を１８０度回転後、再度ストッパー部材を押し下げることでラッチ錠の左右勝手を変更することが可能になる。【選択図】 図１
